角度。 Figures 1a, b, and c are explanatory diagrams showing the rotational movement of the seat cushion and the operation of its fixing device, and Figure 2 is a perspective view showing the fixing device when the seat cushion is in the use position. FIG. 3 is a perspective view similar to FIG. 2 when the seat cushion is brought into the storage position, and FIG. 4 shows the seat cushion separated from the fixing device. It is an exploded perspective view of a link. 2... Seat cushion, 4... Floor, 6...

Claims

[Claims for Utility Model Registration] A first link whose proximal end is pivotally supported on the floor of the vehicle body, a second link whose one end is pivotally connected to the distal end of the first link, and the first link. a third link whose proximal end is pivoted to a floor portion on the rear side of the link, and whose distal end is pivoted to the other end of the second link, the first link, the second link, and the third link. The three links and the floor constitute a four-bar chain, and the seat cushion rotates between a substantially horizontal use position and an upright storage position as the first link rotates. The front end of the lower surface of the seat cushion is fixed to the first link, and the seat cushion rotates from the use position to the storage position, and the angle formed by the second link and third link is 1.
A seat cushion fixing device for an automobile, characterized in that a stopper means is provided for prohibiting the relative movement of these links and restraining the four-bar chain to fix the seat cushion in a stored position when the angle exceeds 80 degrees. .
